try this

select 1 + cast(ISNULL(MAX(SesionID), 0) as float) as SessionNew
from CONTROL.dbo.tblProgressHx

if you really want it in a variable then

DECLARE @sessionId int

select @SessionID = 1 + cast(ISNULL(MAX(SesionID), 0) as float) as SessionNew
from CONTROL.dbo.tblProgressHx

PRINT @sessionID


Thanks
